PatentedlViay 3, 1932 UNITED STATES PATENT OFFICE ADQLBH POTDEVIN, O1 GARDEN CITY, NEWYOBK ASSIGNOR T POTDEYIN MACHINE COMPANY, BROOKLYN, NEW YORK, A 'COBPORATION OF NEW YORK PASTE FOUNTAIN Application filed July 10,

objects the provision of an improved construction wherein clogging of the paste regulating aperture due to paste lumps forming I. provide also a constructionwherein the paste feedin roller is adjustable, means being provide however, whereby the extent 'of adjustment is limited by safety bearing surfaces so that injury to the lump crushing mechanism is eliminated.

In the accompanying drawings I have shown two embodiments of my invention.

Fig. 1 is a part sectional side elevation of one embodiment of my invention;

Fig. 2 is an end elevation of the of the fountain of Fig. 1;

Fig. 3 is a plan view of the mechanism of Fig. 1 with part of the roller-broken away;

Fig. 4 is a fragmentary sectional'side ,elevational view of a modification; and

Fig. 5 is a fragmentary plan view of the embodiment of Fig. 4. 7

Referring first of all to the embodiment roller end of my invention illustrated in Figs. 1 to 3,

inclusive,it will be seen that my invention provides a paste pan 1, and paste feeding roller 2. v

The roller 2 adjustably mounted in eccentric bearings 3. By backing out thumb screws 4, the roller canobviously be adjusted vertically with respect tothe clearance between the roller periphery and the edge 5 of the pan 1. 7

On the face of the roller I provide a crushing member or bar 6. This member as will be seen from Figs. 1 and 2 extends length wise of theroller, terminates an appreciable distance from the ends thereof, and projects throughout itslength from the roller periphery. I

A recess 7 provided in the pan 1 for accommodating the crushingmember 6.

The back wall of the pan at the recess 7 is cutback slightly as shown at 8 so as to provide somethm of a wedge-shaped space between the crus ing bar 6 and the pan, to promote the crushing action of the bar, thereby preventing the forming of dry sections or until the crushing bar hits the pan, because T w of the fact that the ends'of the roller beyond the bar will contact with the pan before the roller has been lowered to this extent.

It will be seen, therefore, that I have pro- 1 v ded a paste fountain of improved cOnstruction, employing a crushing member for crushing any lumps which form in the paste, means being provided whereby adjustment of the roller to a point where the bar will jam is prevented. 1 I In the embodiment of my invention illustrated in Figs. 4. and 5, the paste feedin roller 9 is provided integrally withraise crushing portion 10, depressed paste feeding surface 11, andv raised circular surfaces 12 1 level with the portion 10, thus preventing the jammin of portion 10 against paste regulating edge 15.

The'pan 13 as shown at 1 1 is shaped similarv to the formation provided in Fig. 1 whereby a wedge-shaped space is provided between the crusher and pan to ensure crushing of th paste lumps. 7 It is to be understood that changes may be made in the detailsof construction above described within the purview of my inventlon.

What I claim is 1. In a paste fountain, the combination of a paste pan, a paste feeding roller adjustable relatively to the paste pan, the periphery ofsaid roller being provided with a paste transferring portion or surface and with'lump crushing means, the latter cooperating with the edge of the paste pan, and means for pre- 9 venting engagement of the lump crushing means with the pan in adjusting the roller.

2. Ina paste fountain, the combination of a paste pan, a paste feeding roller adjustably mounted on said pan, a crushing member mounted on and projecting from'the face of said roller and cooperating with the edge of the paste pan, the face of the roller beyond 7 the ends .of the crushing member being engageable' with the pan to prevent engagement 2 vertically. it'is of the crushin -member with the pan in adjusting the rol er.

a paste pan, a paste feeding roller adjustably mounted thereon, a crushing member on the face of the roller, said pan being provided with a surface cooperating with the crushing member to provide a wedge-shaped space for the entry of paste lumps to be crushed, this wedge-shaped space providing for the crushing action on the lumps to be progressively increased, a portion of said roller when the rolleris moved to its extreme position toward the pan beingadapted to engage the pan to prevent contacting of' the crushing member with the pan.

4. A paste fountain comprising a paste pan, a roller adjustable relatively thereto, said roller being provided on its periphery with a depressed paste feeding surface, and intermediate its ends with a raised lump crushing surface cooperating with the pan, the periphery of the roller at each side of the lump crushing surface being provided with raised safety bearing surfaces adapted to engage the pan in the adjustment of the roller toward the pan for preventing contact of the lump crushing surface with the edge of the pan.

This specification signed this 8th day of July, 1929.
